GAS-GENERATING OIL-BURNER.

Specification of Letters Patent.

Patented May 1, 1917.

Application led September 18, 1916. Serial No. 120,670.

To all whomiz't may concern.' f Be it known that I, CARL CHARLES, a at State of Kansas, have invented certain new and useful Improvements in Gas-Generating Oil-Burners, of which the following 'is a specification.

This invention relates to gas generating oil burners, and has for its object to produce an efficient and inexpensive burner for use` in heating stoves, furnaces and the like. A further object is to produce a burner of simple and compact construction which can be easily placed in or removed from the combustion chamber of a stove or furnace.

With these objects in viewthe invention consists in certain novel'and peculiar features of construction and organization of parts as hereinafter described and claimed;

' and in order that the invention may be fully equivalent absorbent non-combustible mateunderstobd reference is to be had to the accompanying drawing, in which:

Figure 1, is a top plan view of a burner embodying the invention.

Fig. 2, is a section taken on the 'line II-II of Fig. 1. p

'In the saiddrawing, 1 is a shallow pan which may be of circular form as shown or of any other suitable or preferred configuration, and said pan is adapted to rest upon the grate or other support of a stove or furnace. Preferably thepan is provided Iwith a number of depending or supporting lugs or feet 2 and with a central opening 3. It is also provided with a lining 4 of asbestos or rial.

Arranged horizontally at a suitable height aboveand centralized with respect to the pan is a generator 5, which conforms preferably in contour to the pan, and the space encircled by the generator is closed by a plate or web 6 preferablyv cast with the generator, said plate or web constituting the top of a mixing chamber hereinafter more 4 particularly referred to.

At diametrically opposite points the generator is provided with tubular nipples 7 and 8, the same being internally threaded to respectively' receive elbow pipes 9 and.l0, elbow 9 being screwed upon the upper end of a vertical pipe 11 connected bynfelbow 12 to an oil supply pipe 13, leading from' an oil tank, not shown. The oil may flow from the oil tank through the force of gravity or may be forced to flow by the use of compressed air or otherwise, and pipe 13 will be controlled by a needle valve, not shown, whereby the flow of oil may be regulated and controlled. As the use of an oil supply tank and a regulating valve is not new in this class of appliances, neither have been shown. The pipe 13 contains a filter 14 to filter the oil before it reaches the burner proper, and said filter will also serve as an obstruction to back iow ofoil or gases when pressure is produced in the generator, in order that the flow of 0fas to the mixing chamber hereinbefore referred to, shall be steady and uniform and without pulsation.

The lter 14 preferably consists of fine wire gauze rolled to cylindrical form and tted snugly in pipe 13.

Extending vertically downward from and secured to elbow 10 is a pipe 15 and said pipe is connected by an elbow 16 to a horizontal .pipe 17 overlying and slightly spaced from the pan 1, and screwed on the inner end of and is engaged at its lower end by a cap nut 20 which thus effects the' clamping of the coupling firmly to the pan.

The upper end of the coupling is provided with a reducing lu 21 and screwed upon the upper endo said plug is a gas tip 22, said tip having a fine jet orifice 23 in its center through which oil can flow slowly and vapor can be discharged forcibly under pressure developed in the generator.

` The generator is provided with a depend ing flange 24 upon which is fitted' tightly with a gas tight relation a cylindrical burner head 25,.-ind depending centrally from and communicating withthe burner head is a mixing tube 26. The'burner head is provided with a series of jet orices 27 below the flange 24, and to secure said head in position it is provided with outwardly projecting lugs 28 fitting against the lower sides of nipples 7 and 8 and secured to said nipples by screw b^lts 29. Assuming that it iS desired to operate the burner, the controlling valve willhbe opened to permit oil to flow readily.

flow through the supply pipe to the generator, and thence from the latter to the coupling 1S and overflow through the orifice 23 down into thepan uponwhich it will quickly spread owing to the absorbent character of the lining of the pan. When the pan is suliiciently charged with oil, the operator closes the controlling valve and drops a lighted match or paper into the `pan. This ignites theoil which may be coal oil or distillate or any other oil sufficiently light to The flames from the burning oil will rise and envelop the burner head and generator and the adjacent portions of the pipes connected thereto and soon raise said parts to vaporizing temperature. 'This con'- dition Willbe apparent to the operator by a change in the color of the flame, that is-to say the initi-al yellow or red flame produced by the burniiig oil will give place to a blue flame issuing from the jet orifices27, owing to the fact that the oil will collect in the bottom of the generator 5 and will be vaporized and the vapor will force its Way to the coupling 18 arid be forcefully ejected through the orifice 23 up thrugh the mixing tube 26 into the mixing chamber, of the burner head. In 4this passage the vapor'will draw air through the mixing tube into the mixing chamber,` and the mixed air and vapor will issue from the orifices 27 as a combustible gas. When the color of the flame changes as explained, the operator will immediately reopen the controlling valve to permit the oil to flow from the tank to the burner, which oil when it attains approxi mately the level of' the top of pipe l1, will be converted into vapor and thence flow through the generator and from th same to the coupling` 18 and be forcefuly discharged up through the mixing tube into the mixing chamber, drawing air into the mixing chamber as explained. The gas thus produced is discharged as explained from the orifices 27, the lengthof the flames being determined by the quality and 'quantity of the oil supplied, it being apparent that as long as the controlling val've is open the heater will operate, and that it will maintain th'e upper part of the device atlvaporizing temperature.

From the above description it will be apparent that- I have produced a device oi" the character described, possessing the features of'advantage enumerated as desirable, and I wish it to be understood that while I have illustrated and described the preferred embodiment of the invention I reserve the right to vmake all changes properly falling within the spirit and scope of the appended claims.

1. A gas generating oil burner, comprising a pipe line terminating in a tip provided witli an orifice for discharging-upwardly, said pipe line embodying two verticallyvdisposed portions at opposite sides of and spaced from said tip, a pan4^ underlying said vertically disposed portions of the pipe line and the discharge end thereof and secured in fixed relation to the latter, a circular generator forming a part of the pipe line and interposed between and connected at diametrically opposite points to the upper ends of the vertically-disposed portions of the pipe line and centralized with respect to and located in a higher plane than said tip; said circular generator having a central im# perfor-ate portion or web and a'depending,

circular flange, and a cylindrical burner head fitting with a gas-tight relation around and firmly secured to said flangeand provided in a lower'plane than the latter withl pipe lin'e embodyingtwo verticallydisposed portions at opposite sides 'of and spaced from said tip, cally disposed the discharge fixed relation end thereof and secured in to the latter, a circular generator forming a part of the pipe line ,and

interposed bet-Ween and connected at dialnet rically opposite points to the upper ends of the verticallydisposed portions of the pipe line and centralized with respect to and located in a higher plane than said tip; said circular generator having a central imperfoi-ate portion or web and a depending c1rcular flange, a cylindrical burner head fita pan' underlying said verti# portions of the pipe line and ,y

ting with a gas tight relation around said flange ,and provided in a lower plane than the latter with a horizontal series of radial orifices and with a depending mixing tube terminating above and centralized with respect to said tip, lugs extending outward from the burner head at opposite sides thereof and screws securing. saidlugs firmly to the generator.

In testimony whereof, I aflix my signature, in the presence of two Witnesses.

CARL CHARLES.
